目的:探讨输尿管软镜碎石术后石街形成的原因及处理方法。方法:2013年7月~2014年12月采用输尿管软镜碎石术治疗338例,术后复查发现有5例患者出现输尿管石街,其中男4例,女1例,平均年龄51岁。4例为单侧肾结石,1例为双侧肾结石,结石长径1.5~3.5cm,平均2.8cm,平均手术时间85min;石街长3~12cm,予行输尿管镜取石术,3例患者术中发现结石聚集成团块状,需再次用钬激光击碎梗阻结石后用套石篮套出碎石,2例患者结石聚集较疏松,予套石篮使其松动后逐一套出输尿管。结果:5例患者术后结石全部清除,2周后拔除留置的双J管,患者痊愈。结论:结石较大,粉碎不够彻底,肾内血块或渗出物未及时清除及术中输尿管有损伤是术后石街形成的主要因素,术中应注意避免。
Objective: To investigate the causes and treatment of stone street after ureteroscopic soft lithotripsy. Methods: From July 2013 to December 2014, 338 cases of ureteroscopic lithotripsy were treated. Ureter stone street was found in 5 cases after operation, including 4 males and 1 females, with an average age of 51 years. 4 cases of unilateral kidney stones, 1 case of bilateral kidney stones, stones with a long diameter 1.5 ~ 3.5cm, an average of 2.8cm, the average operation time 85min; Stone Street length 3 ~ 12cm, ureteroscopic lithotomy, 3 patients Found in the stones gathered into clumps, need to once again with holmium laser crushed obstruction stone with a stone set out of the stone, two patients with loose stones gathered more, set the stone basket to loosen one by one out of the ureter. Results: All the 5 patients were completely removed after operation. Two weeks after the removal of the double J tube, the patient recovered. Conclusion: The larger stones, incomplete pulverization, the timely removal of blood clots or exudates in the kidney and the injury of the ureter during operation are the main factors in the formation of Stone Street after operation, and should be avoided during operation.
